I notice that on some shows, the stuff I wanna watch acts as though I do not have premium even though I do. It says on my account it is active premium until the 20th this month.

The show i'm currently trying to watch that has this issue is:
It tells me to buy premium to see the episode when I have premium already.

Laenri, I believe that's because actually a drama series and you only have the premium membership for the anime here on the site. To access the premium drama simulcast you need to have a drama membership or the All-Access Membership.
